Abstract: ABSTRACT OF THE DISCLOSURE      A setting tool is shown of the type adapted to be made  up  in  a  pipe  string  for  releasably  engaging  a setting  sleeve  in a well  bore.   The  setting tool  is designed to set a liner hanger using right hand as well as left hand rotation and is released from the setting sleeve  using  right  hand  rotation.    A  plurality  of retractable,  spring loaded torque  fingers carried on a torque collar are used to transmit torque to the setting sleeve but, are moved into a retracted position after the setting sleeve is released to avoid damage to the torque fingers.    A  plurality  of  splines  and  a  splined  ring within the torque collar are used to latch the tool in the running-in position to perform well bore operations, such as hanging a liner.   The splines and splined ring have  specially  mating  surfaces  which  form  a  key arrangement  to  facilitate  reinsertion  of  the  splines within the splined ring for subsequent operations as the tool is manipulated between the running-in and weight set down positions.

Abstract: ABSTRACT OF THE DISCLOSURE Nylon carpet fibers are provided which resist staining by acid dye colorants at room temperature, yet are dyeable at elevated  temperatures  with  acid  dyes  without  losing  their resistance to acid dye colorants at room temperature.  The fibers are  characterized  by having a  coating  on  the  surface  thereof comprising  one  or  more  selected  compounds  (stain  blockers). Carpets comprising the fibers resist staining when exposed for long periods of time to spills containing acid dye colorants.  By also including a fluorochemical in the coating, the carpets can resist such staining even after being subjected to heavy human trafficking.

Abstract: Abstract Titanates of barium, strontium, or mixed barium and strontium consisting essentially of solid, non-aggregated particles having diameters ranging from 0.05 to 1 micron and a narrow particle size distribution expressed by the polydispersion index, dw/dn, not greater than 1.20, where dw is the weight average diameter and dn is the number average diameter, said particles being essentially perfectly spherical with a total mean axial ratio of at least 0.930. These titanates are prepared by a process which comprises precipitating of a peroxidic precursor having the same morphological characteristics of the titanates.  The peroxidic precursor is obtained by heating an alkaline solution comprising a complex of a titanium compound with a peroxidic compound, an M2+ compound, wherein M is Ba, Sr or mixtures thereof, and a compound Z capable of complexing with the M2+ ion and oxidizable by the peroxidic compound under the conditions of reaction to produce soluble decomposition products and provide a homogeneous precipitation of the peroxidic precursor comprising titanium and M2+. Subsequently the precursor is heated to a temperature of at least 100°C to obtain the corresponding titanate having the above-indicated morphological characteristics.

Granted: 1990-07-24
Abstract: ABSTRACT OF THE DISCLOSURE            The measuring apparatus comprises a base plate member including a rotatable measuring object receiving station adapted to rota-tably receive e.g. a tool to be measured. Besides the receiving station, a guiding column is arranged having a guiding rail along which a measuring carriage is movable upwardly and down-wardly. The carriage is provided with a horizontally displace-able measuring rail, an end portion thereof being equipped with a measuring calliper assembly. This assembly includes a measur-ing calliper with a calliper head which may be brought into contact with the tool to be measured. The calliper head is dis-placeable with regard to a calliper portion fixed to the end portion of the measuring rail. A force acting on the calliper head in horizontal direction (e.g. towards the right) causes the same displacement of the calliper head as a force acting on the calliper head in vertical direction (e.g. upwardly). The displacement is determined by means of a measuring gauge. With the measuring apparatus of the invention, objects may be mea-sured in three dimensions without the need to constructionally change or readjust the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE      A latching arrangement is provided in a high speed battery charging circuit.  The latching arrangement includes a momentary switch for momentarily changing a voltage level on a gate controlling capacitor for a gate controlled high current path and an inversion circuit between the capacitor and the gate, thus permitting a voltage provided by a thermostatically controlled switch to be applied to the capacitor for controlling the gate.          The thermostatically controlled switch senses battery cell temperature and permits fast charging for temperatures below a threshold.   The momentary switch is momentarily activated to initiate the fast charging operation.  Upon sensing a temperature rise, the thermostatically controlled switch terminates fast charging and initiates trickle charging.  When the battery cell cools and the thermostatically controlled switch again closes, the latching arrangement prevents resumption of a fast charge operation.

Abstract: An aerobic microbiological method in which a microorganism (2) is immobilized in a fluid-permeable fiber matrix (1) and supplied with a substrate solution (6) and an oxygen-containing gas (10) which are supplied to and leave the matrix as separate flows mutually at an angle of at least 10<o> and are brought into cross-flow contact with each other and with the microorganism (2) within the matrix (1). The fiber matrix preferably consists of mineral wool. The microorganism is immobilized in the matrix by being introduced in a, preferably conically, precompressed matrix which after introduction of the microorganism is further compressed to fix the microorganism in the matrix. Additionally, it is preferred to adjust the volume of the matrix during the course of the microbiological method in dependence upon the growth of the microorganism. This adjustment may be effected such that the pressure drop of the air flow (10) when passing through the matrix (1) is maintained constant.

Abstract: Reflector fitting with a reflector 1 for one or more light sources 2, in particular a luminous tube. The first main part 3 of the reflector is parabolic and reflects the light obliquely downwards in a first main direction. The second main part 4 of the reflector is divided into two concavely rounded sections 5, 6. The section 6 located at a distance from the first main part 3 comprises parabolic zones 6a-6c which, with an increasing distance from the luminous tube 3, reflect the light with successively increasing deflection downwards in said first main direction. An outer zone 6d reflects the light obliquely downwards in a second main direction. The second section 7 comprises parabolic zones which reflect the light essentially downwards zone 7a or obliquely downwards zone 7b in the second main direction. A zone 7c above and behind the luminous tube 2 reflects the light one or more times in adjacent zones 7a, 7b and/or the first main part 3 and obliquely downwards in the first main direction. The luminous tube is located in the central plane 12 of the reflector. The reflector 1 can be turned in order to emit asymmetrical light to the right or the left or, in the case of double mounting, to emit symmetrical or asymmetrical light. Fig. 4. <IMAGE>
